(c): Let C.P =x $\therefore S.P=1.2x$ Bought at 20% less $C.\text{ }P.\Rightarrow C.P.'=0.8x$ Sold at$\left( 1.25x-5 \right)$ $\Rightarrow Gain=\frac{\left( 1.2x-5 \right)-0.8x}{0.8x}\times 100%=25%$ $\Rightarrow \frac{0.4x-5}{0.8x}=\frac{1}{4}$ $\Rightarrow 1.6x-20=0.8x$ $\Rightarrow 0.8x=20$ $\Rightarrow 1x=25/-$
